Zeta ai and Y/N

Hii!!
I’m here to ask a few questions regarding Zeta AI and Y/N.
I absolutely love Zeta AI because of its responses. They’re long, but not too long, and if you’ve used Zeta AI, you probably know what I mean. The replies are expressive, descriptive, and full of depth. They don’t feel cold or repetitive, and the conversations actually feel alive.

So why don’t I use it? Mainly because of the memory issues. After around 15 replies at most, every bot I’ve talked to seems to forget everything we’ve built up, which completely breaks the immersion.

Now, about Y/N. I also really like it, but the problem is that the messages feel short, repetitive, and kind of empty. They often come across as cold and lacking personality.
Does anyone know how I could make Y/N bots more expressive and give them more depth? I’d love for the responses to feel more immersive and emotionally engaging.
